Description

The SMP1302-087LF is a surface-mountable, low-capacitance

silicon PIN diode designed as a series-connected PIN diode for

high-power, high-volume switch and attenuator applications from

10 MHz to beyond 6 GHz.

Maximum resistance at 100 mA is 1.5 Ω and maximum

capacitance at 30 V is 0.35 pF. The combination of low

capacitance, low parasitic inductance, and nominal 50 μm

I-region width, makes the SMP1302-087LF useful in large signal

switches and attenuator applications.

The device has a 1 W dissipation power rating, which makes it

capable of handling up to 125 W @ 25 °C Continuous Wave (CW)

in a series-connected transmit/receive (T/R) switch.

Design information for high power switches may be found in the

Skyworks Application Note, Design With PIN Diodes (document

number 200312).
